| + | * Found 0 ohm resistor (pkg 0805) | ||
| + | * Tested using heat lamp | ||
| + | * Voltage across VCC on the charging ckt (on board) spiked whenever we turned on the heat lamp to simulate the sun | ||
| + | * Spiked to ~6.4V and suddenly dropped back down to ~4 V | ||
| + | * This could be one of the problems why the board keeps dying | ||
| + | * Potential solutions: | ||
| + | * Capacitor (choose a right value?) | ||
| + | * If the voltage spike is due to current, we could use an Inductor | ||
